BIO-METALLIC TUBE TYPE STENT FOR THE TREATMENT OF PERIPHERAL VESSELS

摘要

PURPOSE: A bio-metallic tube type stent for treating peripheral blood vessels is provided to ensure sufficient elastic force and to easily return the shapes of vessels regardless of pressures. CONSTITUTION: A bio-metallic tube type stent for treating peripheral blood vessels includes closed cell structure parts(10), struts(20), and link parts(30). Closed cell structures and opened cell structures coexist in the closed cell structure parts. The closed cell structure parts are disk-shaped, and the struts are zigzag-shaped. The link parts connect the zigzag-shaped struts and the disk-shaped closed cell structure parts. The link parts are diagonally connected. The lengths of the link parts are extended such that peaks, at which struts meet, have half-phase differences.
